Direct and inverse proportions class 8 formulas / Direct and inverse variation
These formulas are essential to solving problems related to Direct and Inverse Proportions. The first formula for direct proportionality shows that if two variables x and y are directly proportional, then they can be related by a constant of proportionality k. The second formula shows that if the ratios of corresponding values of x and y are equal, then the variables are directly proportional.
The first formula for inverse proportionality shows that if two variables x and y are inversely proportional, then they can be related by a constant of proportionality k. The second formula shows that if the product of corresponding values of x and y is constant, then the variables are inversely proportional.
The joint variation formula is used when a variable z depends on two variables x and y jointly. The combined variation formula is used when a variable z is affected by two variables x and y, but in opposite ways. By understanding and applying these formulas, you will be able to solve Direct and Inverse Proportions problems more efficiently and accurately.
